COGNITIVE SKILLS WITH SPECIFIC REFERENCE TO MECHANICAL
TECHNOLOGY
ENGAGEMENT: Explain and illustrate how the Loss and as facilitate cognitive and conceptual development within and across grades TIME ALLOCATION: 45 minutes RESOURSES: Worksheet METHOD (S): Presentation, working in pairs
INTRODUCTION (10 minutes) • At the end of this activity you will be able to understand and identify the levels of
Bloom’s taxonomy by examining the assessment standards. • Cognitive strategies are procedures used for discovering knowledge. Benjamin Bloom
and his associates developed a classification of learning outcomes, which is still useful for both research and teaching. Bloom’s taxonomy pertains to the cognitive objectives of instruction and divides them into several types. These range from goals referring to relatively concrete intellectual skills to ones referring to very abstract thought.
Bloom classifies learning into the following categories:
1. Knowledge – the ability, on request, to remember, recall, or recognise facts
or ideas.
2. Comprehension – the ability to use knowledge that is remembered more or less as it is originally presented and intended to be used.
3. Application – the ability to use general ideas or principles in particular situations.
4. Analysis – the ability to separate the elements of an idea or passage and to examine each one individually.
5. Synthesis – the ability to combine elements into greater structures or wholes.
6. Evaluation – the ability to judge how well ideas and materials satisfy certain criteria.
ENGAGEMENT (25 minutes)
INSTRUCTIONS: • Participants organise themselves into pairs. • In the table below, column A contains a list of assessment standards across all grades. • Participants must identify which level of Bloom’s Taxonomy appears to be addressed
by the following extracts from the assessment standards. • Use the verb in the assessment standard to guide you.
